Application filed June 16, 1921. Serial No. 178,067.

Closing Mechanism, of which th'e'followin'g is a specification.

This inv'entionrelates to gates, and the primary object of'the inventionis to provide an improved and novel means for opening and closing gatesat points remote therefrom, whereby persons in vehicles approaching orleaving the gates, can open or close the same, without the necessity ofgetting out of the vehicle;

Another object of the invention is the provision of a novel meansfor'supporting the gate, to permit the sameto'be readily opened andclosed, and toxpermit'the same to be raised and adjusted in relation tothe ground or road way, so as. to overcome any sagging in the gate, ortolift'the same over obstructions in the roadway.

A further object of the invention is to provide a novel (iperatingdevice for gates comprising means arranged laterally on each side of thegate, and means arranged forwardly or rearwardly of the gate, wherebythe gate can be conve'niently used on cross roads and the like; i

A still further object of the invention is to provide an improved gateoperating mechanism of the above character, 4 which will be durable andefficient in use, one that will be simple and easy to manufacture, and

one which can be placed upon the market at a reasonable cost. I

With these and other objects in view, the invention consists in thenovel construction,

' arrangement and formation of parts as will be hereinafter morespecifically described, claimed and illustrated in the accompanyingdrawing, forming apart of this specification, and in which drawings:

Figure 1 is a perspective view of theimproved gate and operating meanstherefor, the gate beingshown in partly opened position.

Figure 2 is a fragmentary detail perspective view of one of thesupporting uprights for the gate.

Figure 3 is a fragmentary vertical section through one of the supportingposts or up: rights for the gate illustrating themeans for attaching theoperating ropes."

Figure 4C is a similar view showing the means of associating thesupporting rollers therewith.

Figure 5 is a fragmentary side elevation of one of the standards forcarrying the operating ropes. V.

Figure 6 is a fragmentary side elevation of the shears utilized forsupporting the supporting rod for the gate.

Referring to the drawings in detail,

wherein similar reference characters desig nate corresponding I partsthroughout the several views, the letter A indicates the gate; B, thegate carrier; and C, the operating device for the gate.

The gate A can be of any preferredconstruction, and is adapted to slidetrans-- versely across the roadway D, which is shown branching off froma main roadway E. This gate is adapted to normally close an opening inthe enclosing fence F, which as shown includesend posts 10, one of whichcan be provided with a suitable guide 11 for the gate A. r

As shown the gate A includes end posts 12 connected by panels 13, but asheretobefore stated, the gate can be constructed in any 12, if sodesired. While the uprights 14 can I be of any desired construction orformation, the same have been shown solid and pro vided with thevertically extending aligned slots 15.

The gate carrier or supporting means B comprises a pair of shears l6 anda pair of shears'17, and theseshears are located on the opposite sidesof the roadway. Each of the shears include a pair of. legs 18 which arepivotally connected adjacent to their upper ends by means of a pivot pinor bolt 19. These pairs of shears 16 and 17 are adapted to support therod or supporting cable 19, which is adapted to extend transverselyacross the roadway D above the gate A and is extended through the slots15 formed in the uprights 14. The opposite ends of the spacedtransversely extending openings 21,

certain of whichoare adapted to receive suitable removable bolts 22,which support rollers 23 which are adapted to engage the sup:

necessary to move the lower portions of the legs 18 of the shears closertogether, which will effectively raise the supporting rod or cable 19.The upper ends ofthe uprights 14 are braced by an upper beam'24, theterminals of which .are'also extended in the side portion 15 of theuprights, and these terminals can be held infplace by means of or onhorse back.

suitableremovable bolts 24, which can be inserted in any one of theopenings 21. Suitable bolts 25 are also inserted in the openings 21above the bolts 24, and these bolts 25 serve as meansfor permitting theoperating ropes to be secured to the gate, as will be hereinafter morefully described. It canbe seen that there are two of the bolts 25, oneat each end of the gate.

The operating means C for the gate A includes a plurality of pull ropes,and these ropes are so disposed as to permit the gate A'to be operatedatv either side of the gate, laterally thereof, or rearwardly of thegate, as clearly shown in Figure 1 of the drawings.

Thus it can be seen that the gate A can be operated from three differentpoints. Standards 27 and 28 are arranged on each side of the gatelaterally thereof, anda standard 29 is arranged rearwardly of the gate.The standards are disposed a suflieient dis tance from the gate topermit the gate to be conveniently operated by persons in vehicles Eachof the standards 27, 28, and 29 is provided with an outwardly extendingarm 30, which is suitably braced in order to prevent sagging thereof.The standard 27 is provided with a pair of guide pulleys 81 and 32, thestandard 28 with a pair of guide pulleys 33 and 34, and the standard 29to a pair of guide pulleys 35 and 36. An intermediate standard 37 isarranged at one side of the gate opening and between the standard 27 and28, and this standard can be secured to one of the gate posts 10 or forma continuation thereof. This post is also provided with a laterallyextending arm 38, to which is secured a triple block 39. The upper endof one leg 18 of the shears 16 is provided with a pair of pulleys 40 and41, while the upper end of the oppositeleg is provided with a pair ofpulleys 42 and 4 3. In order to open and close the gate I fromtheleft-handsideof the read, an ad jus ble rare 4 p ov ded. which istrained amen he P} 1l y- .l ,;a ,oun 11 e lower P111- ley 41, around oneof the pulleys of the triple block 39 carried by the intermediatestandard 37, and then back and secured to the bolt 25, which is arrangedat the upper end of the standard 14 at the forward end thereof. It canbe seen that by giving this rope 44 a downward pull, the gate will heslid rearwardly on' the cable or rod 19. When it is desired to close thegate from the left hand side, the rope 45 is pulled, which will betrained around the pulley 32, around the upper pulley 40, and thenextended directly to the bolt 25 at the forward end of the gate. Thus itcan be seen that a pull upon this rope 45 will move the gate to itsclosed position. i

In order to permit the gate to be operated from the right hand sidethereof, a pair of cables 46 and 47 are provided. The cable 46 istrained around the inner pulley 33, around the pulley 48 carried by oneof the legs 18 of the shears 17, around pulleys of the triple block 29and then back to the bolt 25 carried by the upright 14 at the rear endof the gate. It can be seen that when a pull is exerted on the rope 46,the gate will be slidto its'closed position. The rope 47 is trainedaround the pulley 34, around an upper pulley 49 carried by one of thelegs 18 of the shears 17, and secured directly to the bolt 25 of theupright 14 arranged in the rear end of the gate A. It can be seen thatwhen a pull is exerted on the rope 47, that a direct rearward pull willbe given to the gate thus pulling the same to its open position.

In order to prevent opening and closing of the gate from a pointrearwardly thereof, pulling ropes 50 and 51 are provided. The rope 50 istrained around the pulley 35, around the lower pulley 43 carried by oneof the legs, of the shears 16 and extended directly to the bolt 25carried by the upright 14 arranged in the forward end of the gate. Thusit can be seen that when the rope 50 is pulled, a direct forward pullwill be given to the gate, which will move the same into closedposition. I The rope 51 is trained around the pulley 36, around theupper pulley 42 carried. by one of the legs of the shears 16 and thencearound one of the pulleys of the triple pulley 39, and then back towardthe forward end of the gate, and secured to the bolt 25 earriedby thepost 14 arranged at the front end of the gate. It can be seen that whena pull is exerted on the rope 51, that a rearward pull will be exertedon the gate, which will move the gate to its open position.

From the foregoing description, it can be seen that a novel gate hasbeen provided, whichcan be opened or closed at three different points ina convenient andexpeditious manner, and which can be easily raised orlowered without undue difficulty to permit the same to ride overobstructions in the path thereof, such as stones, snow or the like.

Changes in details may be made without departing from the spirit orscope of this invention; but,

I claim:
